Describe the change. Keep everything else.
Upload a photo, add up to three more references if you need them, and write what should be different. PixMythos tries to preserve the subject and composition of the image you gave it instead of generating a new one from scratch.

Most AI image tools start over every time you press the button. That is fine for making something new, but it’s the wrong tool when you already have a photo you like and want to change one thing in it.
The editor works the other way around. You give it the image, and you tell it what to change and what to leave alone. The better your instruction separates the two, the closer the result stays to your original.
Each example shows the exact prompt we used, so you can reuse it or adapt it. Every pair below was made in the editor from the image or images on the left.
Prompt
Keep the woman's face, hair and clothing exactly as they are. Replace the background with an overcast city street at dusk. Match the lighting on her to soft, cool daylight.
What changed: The background and the light on the subject. What stayed: Face, hair and clothing.
Prompt
Remove the brass floor lamp on the left. Leave the rest of the room untouched, and fill the space with the same wall and wood floor texture.
What changed: One object. What stayed: Chair, side table, artwork, walls and wood floor.
Prompt
Redraw this photo as a soft watercolor painting. Keep the composition and the position of every object. Use muted colors and visible paper texture.
What changed: Rendering style. What stayed: Composition and object placement.
Prompt
Keep the sunglasses' shape, lenses and gold frame exactly as they are. Place them on a marble countertop with warm morning light coming from the left and a soft shadow.
What changed: Setting and lighting. What stayed: The sunglasses' shape, lenses and gold frame.
Prompt
Use the person from image 1. Place them in the location shown in image 2, standing near the left edge. Match the lighting to image 2.
What changed: Location and lighting. What stayed: The person from image 1.
Good edits come from instructions that say three things: what to keep, what to change, and what to match.
Part
What it does
Example
Keep
Protects what you don't want touched
“Keep her face, hair and clothing exactly as they are.”
Change
Describes the one thing to be different
“Replace the background with a rainy street at night.”
Match
Makes the change fit the original
“Match the lighting and perspective of the original photo.”
Change the background.
Keep the man’s face, jacket and pose exactly as they are. Replace the background with a quiet harbor at sunrise. Match the lighting on him to warm, low sunlight from the right.
The second prompt gives the model less room to guess, so there is less to go wrong.
Refer to each image by number: “the person in image 1”, “the jacket from image 2”, “the background in image 3”. If you don’t say which image does what, the model has to guess.
For large edits, run them in steps. Replace the background first, then adjust the lighting in a second pass. Each step is easier to control than one long prompt.
AI image editing is probabilistic. Knowing where it struggles saves you credits.
The same prompt can give different results.
Generate more than once and pick the best.
Small text and logos may change.
If your image contains fine print, a label or a logo, check it carefully in the result.
Faces and hands in busy scenes can need a second pass.
Zoom in before you use the image.
Very large changes work better in steps.
See “Change one thing at a time” above, then refine the result in another pass.
Short answers to common questions about editing images with AI.
It tries not to, but nothing guarantees it. Say clearly what should stay the same, and check the result before you use it.
Use a clear, high-resolution source image, say what to keep, and change one thing per edit. See the guide above.
